Golf club heads and methods to manufacture golf club heads

A golf club head comprising:

• a body portion including an interior cavity, a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front opening at a front portion, a back portion having a back wall portion, a top portion with a top portion edge, and a sole portion with a sole portion edge;
• a face portion coupled to the front portion to close the front opening, the face portion comprising a front surface comprising a plurality of front grooves and a back surface comprising a plurality of back groove portions;
• a mass portion comprising a material having a greater density than a density of a material of the body portion, the mass portion located in the interior cavity and coupled to the back wall portion, the mass portion including a first dimension extending in a heel-to-toe direction, a second dimension extending in a top-to-sole direction and different from the first dimension or the second dimension, and a third dimension extending in a front-to-back direction and being less than the first dimension;
• a port having a port opening on an outer surface of the body portion, the port opening connected to the interior cavity;
• and
• a filler material in the interior cavity, the filler material comprising a material having a lower density than the density of the material of the body portion,
• wherein a distance between the mass portion and the sole portion edge is less than a distance between the mass portion and the top portion edge,
• wherein a distance between the mass portion and the back surface of the face portion is less than a distance between the back wall portion and the face portion at a location above the mass portion, and
• wherein a distance between the mass portion and the port is less than a distance between the port and the heel portion edge.

An iron-type golf club head comprising:

• a body portion having a volume of less than or equal to 100 cubic centimeters, the body portion including an interior cavity, a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front opening at a front portion, a back portion having a back wall portion, a top portion with a top portion edge, and a sole portion with a sole portion edge;
• a face portion coupled to the front portion to close the front opening, the face portion comprising:
• a front surface comprising a plurality of front grooves;
• a back surface comprising a plurality of back groove portions;
• and
• at least one transverse portion extending in a front-to-back direction and defining a portion of the toe portion, the top portion, or the sole portion of the body portion;
• a non-cylindrical mass portion comprising a material having a greater density than a density of a material of the body portion, the mass portion located in the interior cavity and coupled to the back wall portion;
• a cylindrical port having a port opening on an outer surface of the body portion, the port opening connected to the interior cavity;
• and
• a filler material in the interior cavity, the filler material comprising a material having a lower density than the density of the material of the body portion,
• wherein a distance between the mass portion and the sole portion edge is less than a distance between the mass portion and the top portion edge,
• wherein a distance between the mass portion and the back surface of the face portion is less than a distance between the back wall portion and the face portion at a location above the mass portion, and
• wherein a distance between the mass portion and the port is less than a distance between the port and the heel portion edge.
